IMPROVEMENT IN PRINTING-PRESSES.

Specification forming part of Letters Patent N0. 43, 196, dated June 2l, 18611.

To @ZZ whom it may concern:`

Be it known that I, GEORGE I. GORDON, of Brooklyn, in the county of Kings and State of New York, have invented, made, and applied to use certain new and useful Improvements in the Construction and Operation of Printing-Presses; and I do declare the following to be a full, clear, and correct description thereof, reference being had to the accompanyin g drawings, making part of this specification, and to the letters of reference marked thereon, in which- Figure l is a back view of my improved printing-press. Fig. 2 is a side sectional view of the same. Fig. 3 is a side lsectional view of the, same; Fig. 4i, detached view of wheels X X2 Z Z2, shalt C, and roller-frame L.

In the dra-wings like parts of the invention are designated by the same letters of reference.

The nature of my invention consists (a) in the use or employment of a single revolving ink-distributing table operating a second revolving ink-distributin g table, for the purpose of thoroughly and evenly distributing the ink and supplying the same to the revolving inking rollers (b) in the use or employment ofthe revolving inking-rollers in combination with a revolving ink-distributing table or disk 5 (o) in the use or employment of the revolving hiking-rollers in combination with a revolving ink-distributin g table or disk operating a second revolving ink-distributing table or disk; (d) in the use or employment of a vibrating platen, vibrating substantially as shown, in combination with a stationary bed, and a revolving ink-distributing table or disk operat ing a second revolving' in k-distributing table or disk 5 (e) in the use or employment of a vibrating platen, vibrating substantially as shown, in combination with a stationary bed, revolvin ginkin g rollers, and the revolvin ginkdistributing table or disk, or a revolving ink distributing table or disk operating a second revolving ink-distributin g table or disk.

To enable those skilled in the arts to make and use my invention, I will speak of its construction and operation.

A shows a irame for supporting the working parts of my improved printing-press.

B shows the bed, in which is placed the form or types, which bed is supported by the shaft C, passing through the same. y

r1) shows the platen, hun g upon the rod E,

L shows a rollerfra1ne,in which are inserted the rods M, for holding the inkingrollers N. This roller-frame is composed of the side pieces, L, held together by the crossbraces l 2.

O is a support, placed directly over the shaft O and behind the bed B, for the purposeot' supporting the revolving inkdistributingtable or disk P. This revolving ink-distributing table or disk P is provided with the spindle p,

upon which is held the toothed bevel-wheel Q.. y

A rim, q, having rachet-teeth cut upon it, is placed on the under side of the table or disk P, near its periphery. i

R shows a second revolving ink-distributing table or disk, placed in a vertical position at the back of the press, which table or disk is provided with the spindle S, upon which is the toot-hed bevel-wheel T, gearing into the toothed wheel Q upon the spindlep.

U shows a surface-cam placed upon the shaft C.

V is au upright arm, provided with the pawl W, for the purpose ot' operating the inkdistributing table or disk l). The bed B is held iirmly in a stationary position by the shoulders or tubular projections b, which are cast upon and a part of the bed-piece, being iitted tirmly and permanently on each side into the frame A. Through these tubular projections b runs the shaft G, having upon one oi'its ends the small gear-wheel X and the large cogwheel H. The small gear-wheel X `is geared into the gear-wheel Z upon a shaft, whish has upon its opposite end, inside of the frame A, the wheel X2, which gears into the gearwheel Z2. The wheel Z2 is iitted to and revolves upon the tubular projections b, and is attached to the revolving rollerframe L. Thus, motion being given to the shaft (G, the wheelX, through the wheels Z and X2, imparts motion to the wheel Z2, causing the rollerframe L to revolve.

Operation: We will suppose the form or typesv to have been placed in the bed B and the platen D to be in the position shown in Fig. 2 of the drawings, for the purpose of receiving the sheet of paper or card to be printed, and that such sheet of paper or card has been laid upon the platen. Motion being communicated to the press, the platen D, operated by the connecting-rods J, attached as shown, vibrates upon the rod E to the bed B, for the purpose of giving an impression, and continues such vibration until an impression has been taken. An impression having been taken, the platen D, operated by the conneetingrods J, recedes from the bed B to the position shown in Fig. 2 ofthe drawings, necessary to allow the printed sheet to be removed and the succeeding sheet to be laid upon the platen, which, being done, the operation just described is repeated. During this operation of the platen D the inking-rollers N, held and carried in the roller-frame L, attached to the toothed wheel Z2, operated by means of the toothed wheels X2, Z, and X, have been carried over the revolving ink-distributing table or disk R, the revolving inkdistributing table or disk P, and the form or types held inthe bed B, which form or types is properly inked by the rollers N in their Itransit. During the revolution of the rollerframe L the pawl W, (operated by the surface-cam upon the shaft 0,) acting against the rim q, rotates the ink-distributing table or disk P a certain distance, while the second revolving ink-distributing table or disk It is rotated a carresponding distance by means of the gearing Q and T.

The ink-distributing tables or disks P and R may be supplied with ink by means of a hand-roller, and the rotation ot the disks serves to thoroughly and evenly distribute the ink thus supplied.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The use or employment of a revolving inkdistributing table or disk operating a second revolvin gink-distributin g table or disk, for the purpose of thoroughly and evenly distributing the ink and imparting the same to the inkingrollers.

2. The use or employment of the revolving inkin g-rollers, in combination with a revolving ink-distributing table or disk, for the purpose specified.

3. The use or employment of the revolving inking-1ollers,in combination with a revolving ink-distributin g table or disk, operating a second revolving inkA distributing table or disk, for the purpose specified.

4. The use of a platen, vibrating substantially as shown, in combination with a stationary bed and a revolving ink-distributing table or disk, operating a second revolving ink-distributing table or disk, for the purpose or purposes herein shown.

5. In combination with a platen, vibrating substantially as shown7 the use or employment of a stationary bed, revolving inkingrollers, and a revolving ink-distributin g table or disk, or a revolving ink-distributing table or disk operating a second revolving ink-distributin g table or disk, for the purpose specilied.
